There are several things in PR where you can't find in the manual or the "wiki".
Fill in all those things like what will happen with the mines you have deployed when you get killed.
Which maps have a bleed count... and everything else involved with the game.

When being revived inside a house or next to a static move your mouse in a circular motion as fast as you can. Then when the medic goes to revive you the player model will pop out from being glitched into the static first time every time. Saves time trying to use the CPR hands to push you out before trying the revive.

No more "I cannot revive you your heads in a rock." etc

QFT

If you want an accurate map marker when spotting things that you cant see properly, like indicating a target for CAS or armour support...As a squad leader Spot using your 3d marker, check the distance on your caps lock map, equip your radio and right click to activate the distance indication commo rose, take one step faward, and one step back, select your distance and select your enemy target type and the map marker will be placed on your exact 3d marker.

Irons over ACOG. You get a slightly faster scope-up time, you can aim faster, and you are more accurate in CQB.

That's not right. Sight in time is now the same between the two. Deviation is also the same between them, obviously if you don't sight in with the scope you'll be less accurate though.
That said, I do prefer Irons since you don't get tunnel vision when using them.
